Among the recording equipment and memorabilia available to bid on are Schneider's 1964 Volkswagen van, the Panasonic bicycle he rode in the 1984 music video for a remix of "Tour De France," a number of woodwind and brass instruments-including the 1960s Orsi alto flute that appeared on the back cover of Kraftwerk's 1970 self-titled debut-and a rack case of Votrax speech synthesizer units, which the band used to create the robot voices that opened all of their concerts between 1981 and 2002.
